Mentoring is the ability to give advise or train someone, often times, who is less knowledgeable in a particular field. A mentor doesn’t have to be someone who has a ton of experience or a strong grasp over as many fields as possible. Instead of having one person who holds crucial data about a specific feature, which is sometimes referred to as “heroes”, you are at a risk of a substantial loss of knowledge when that person leaves. Mentors actually enjoy seeing their surrounding becoming better at what they’re doing and in part, support a healthy working environment.
